    Resistive force exerted on a sphere (air resistance)

    I equaled the first term to 1% of mg 3.1× 10-4rv = mg/100 and solve to r : r= (10^2) mg/3,1v

    Resistive force exerted on a sphere (air resistance)

    considering that if v is the terminal velocity, the resistive force is equal to weight
